Asthma and obesity are serious medical and social world problems, and their combined course is characterized by a decrease in the quality of life, an increase in the frequency and duration of hospitalization. The present review summarizes the current views on the mechanisms of formation of asthma phenotype combined with obesity, role of leptin and adiponectin imbalance in the development of systemic inflammation in obesity in the pathophysiology of asthma, its interrelations with metabolic syndrome. We present data that shows that syndrome is closely related not only to the debut of asthma, but also to a decrease in its control. Along with obesity, the role of other components of metabolic syndrome, in particular insulin resistance, as a predictor of asthma development is considered. Insulin resistance may be the most likely factor in the relationship between asthma and obesity, independent of other components of the metabolic syndrome. Insulin resistance associated with obesity can lead to disruption of nitric oxide synthesis. We reveal common mechanism of metabolic disorders of nitric oxide and arginine in metabolic syndrome and asthma and show that insulin resistance treatment can be therapeutically useful in patients with asthma in combination with obesity.

: Undeniably, lipid plays an extremely important role in the homeostasis balance, since lipid contributes to the regulation of the metabolic processes. The metabolic syndrome pathogenesis is multi-pathway that composes neurohormonal disorders, endothelial cell dysfunction, metabolic disturbance, genetic predisposition, in addition to gut commensal microbiota. The heterogenicity of the possible mechanisms gives the metabolic syndrome its complexity and limitation of therapeutic accesses. The main pathological link that lipid contributes to the emergence of metabolic syndrome via central obesity and visceral obesity that consequently lead to oxidative stress and chronic inflammatory response promotion. Physiologically, a balance is kept between the adiponectin and adipokines level to maintain the lipid level in the organism. Clinically, extremely important to define the borders of the lipid level in which the pathogenesis of the metabolic syndrome is reversible, otherwise will be accompanied by irreversible complications and sequelae of the metabolic syndrome (cardiovascular, insulin resistance). The present paper is dedicated to providing novel insights into the role of lipid in the development of metabolic syndrome hence dyslipidemia is the initiator of insulin resistance syndrome (metabolic syndrome).

Abstract: Elderly men often show a concurrence of a decline of testosterone with attributes of the metabolic syndrome. This study tested the effects of normalization of testosterone.: A total of 122 hypogonadal men (18–83 years, mean 59.6±8.0 years; n=11<45 years, n=25<55 years, n=53<65 years) were included in the study. Their baseline testosterone levels were between 0.14 and 4.51 ng/mL (n>4.90 ng/mL) and were treated with parenteral testosterone undecanoate for 2 years as the sole intervention (administration at 0 and 6 weeks, and thereafter every 12 weeks).: Plasma testosterone increased from 3.3±1.9 ng/mL to 4.1±1.5 ng/mL (p<0.01) at 3 months, and then stabilized at 6.8±1.3 ng/mL after the first 6 months. There was a remarkable progressive linear decline in body weight, body mass index, and waist circumference over the entire study period. Plasma cholesterol decreased significantly over the first 12 months, and then stabilized. Plasma glucose, triglycerides, low-density lipoprotein cholesterol, and C-reactive protein decreased significantly and high-density lipoprotein cholesterol increased significantly over the 24-month study period in a non-linear manner. There was a significant decrease in aspartate aminotransferase and alanine aminotransferase levels over the first 9 and 12 months, and then values leveled off. Changes in variables were largely correlated with changes in testosterone levels. At baseline, 47 out of 122 subjects fulfilled the metabolic syndrome criteria as defined by the National Cholesterol Education Program (2001); after 2 years of testosterone treatment, this number had declined to 11 out of 122 subjects.: With testosterone treatment over 2 years, the most significant improvement of the metabolic syndrome was noted over the first 12 months, but over the following 12 months further improvement was also observed. With regard to safety of testosterone administration to mainly elderly men, a number of safety measures were carried out.
